To all whomit 'may concern.'

Be it known that ll, JOHN T. NEEDHAM, a subject ot the King of Greatritain, and resident of North Plaintield, in the county of Somerset andState ot New Jersey, have invented certain new and useful llmprovementsin Carriers for Pneumatic-Dispatch Tubing Systems, of which thefollowing is a speciication.

The main object ot this invention is to provide a. carrier with astation-indicating device of simple construction and which will notbecome deranged While the carrier is in transit. Pneumatic dispatchtubing systems frequently comprise a central station and a large numberof outlying stations.v ln such a system it is frequently necessary tosend carriers from an outlying station to the oen-` tral station, whichcarriers are thenl reset to another outlying station. The carriers used'for suoli a. system must be provided with some station-indicatingdevice which can be set by the sending station and which Will'indicateto the central station operatives the outlying station which is the inaldestination ot the carrier. A station-indicating device for such usemust be of very simple construction; must be light and :must be sodesigned that it will not become in any vvay deranged While the carrieris in transit.

j Another object of this invention is to provide a station-indicatingdevice `which will be locked in its set position by the means forretaining the contents of the carrier, so that the saidstation-indicating device cannot become deranged or changed until thecarrier has been opened for the discharge of its contents. l

Another object of the invention is to provide a carrier With astation-indicating device and with a locking means mounted with in thecarrier and completely Vprotected by the carrier While in transit.

There are-other important objects and advantages ot the invention whichwill appear hereinafter.

taken on the line 7-27 of Fig. 2.

According to the various parts by numerals, l designates a carrier bodywhich consists ot a tube of hard ber or other suitable material. T histube is closed at one end by an internal cup 2, the annular flange ofwhich is riveted to the carrier body, as shown in Fig. 2; the other endof the tube is open. To the inner side out the carrier and extendinglongitudinally thereof is rigidly secured a tube or channel 3. rllhistube is preferably secured in place by means ot locks formed thereon andpassed through the body of the carrier, as described in my raten/t ne.1,176,918, dans March es, wie, but not shot/vn herein.. @is course, thistube may be securedl Within the carrier in any suitable manner. Theinner end of the tube or channel 3 is bent laterally and lies close tothe inner side of the cup 2, as shown clearly in Fig. 2, and saidlaterally bent end is apertured 'for the passage of a retaining screw,as will be more fully hereinafter described. Secured Within the innerend of 'the channel 3 and abut-ting against the inner side ot the cup 2is a guide sleeve t; and `within said channel near its outer end is alsorigidly secured a guide sleeve 5.

Loosely fitting over the closed end of the carrier body is a largeindicator cup 6, the annular side of which tits closely against the bodyof the carrier. rEllis cup is 'free to turn on the carrier. Fitting overthe cup tl is an indicator cup 7, the annular side ot which tits closelyagainst the exterior cup t3. The cup 7 is shorter than the cup d so thatthere is al portion ot the cup tl extending beyond the open end of theup 7. A

third indicator cup 8 tits over the cup 7,

this latter cup being shorter than the cup 8, so that a portion ot thecup 8 will extend beyond the open end of the cup 7. llhe cup 8 isrigidly and permanently connected to the telt butler head 9 by means otscrews l0. These screws are countersunlc in the ciosed end of the can 8end ere threaded ing the contents of the carrier.. Thepioching in'o sciainpinp; piet ersnnlr 1n the rod is rotatable in the sleeves e! eno.and outer fece el thehuiier By this means may be drawn outward-y veinstthe tene indicator ciro 8 I turned or rotated with the bui'ifer hea Thebutter head and the three indicator cups are rotatably connected to tieciosure cup 2 the carieri by the screr 'ch passes outwardly through 'heiateraiiy bent part ci' the tube t 3 and through the ciosed ends or niiot the cups and is screwed into the clamp plate 1i. ietween the closedend of the cup 2 and the heed o l e screw 12 is arrcnged a spring plateor Washer 13, so that all; or the parts are ciarnped together byyielding means which insures intimate Contact and frictionat engagement,hut at the seine time per` rnits independent rotation of sii of theindicator cups. The indicator cup 8 and the eX- posed portions of thecups Z and G are provided With a series of indiceting` characters. Asshown in the drawings they are numberedn it is manifest that by rotatingthe indicator' cups independently? any desired arrangement of theninnbers may be secured on the carrier body. in indicatino point ismarked on the carrier cody7 the indicating point shown in the drawing`being in the form of an arrow 14:. By bringing the prop er arrangementof numbers line with the arrow heath the station to which the carrier isto be transmitted will be indicated. order to ioch the indicator cups intheir desired relation to each otheri the closed end of each cup isprovided with series of perforations 15., one for each indicator nurnberplaced on the side of the cup. As shown in the drawings each cup isprovided 'with ten locking apertures 15 one for each nurnber.v Thebuffer head is provided with a series of sockets i6 which register withvthe locking apertures 15 of the cup 8, said Sockets extending asuitabie distance into the buffer head. As the butter head rigidlysecured to the cup 8, the sockets Wili always register with the iochingapertures of the cup.

Slidahly mounted in 'the sieeves 4 and 5 and extending throughthe tubeor channei 3 is a long lockingl rod 17. this rod hetween the sleeves 4-ancl 5 is rigidly secured a collar 18; and between said collar and thesleeve 5 is arranged a coii spring 19, said spring tending to force thelocking rod toward the closed end of the carrier. Rigidly secured to thelocking1 rod near its outer end and beyond its sleeve 5 is a guidesleeve 2O which is adapted to tit Within the channel or tube 3 and willabut against the end ot the sleeve 5 when the rod 1T is in its lockedposition. The locking rod is formed into an arch 21 at its outer end andwith a coil 22 at the base of the arch, said coil being;n adapted to fitwithin the carrier and to serve as a holdingu ciip for the purpose or'retoinsion of the spring' 19. he rod 1'? is of such iength that when itis in its iccv ed positions 'that is to say, when it is fore( i inwardlyto the iiinit of its movement by the ing 19, its inner end will extendthrough the locking perforation in the indicator cups and into one ofthe sockets 1G or the buffer heed and thereby lock the indicating ineensegainst rotation. the coil 22 engaging the end ot the tube 3 andservingr a stop for the rod To release the iocking means, the arch 21 isgrasped `and the locking rod is drawn outwardly against the tension ofthe spring" 19. Then the hoidinfreiip coil Q2 has been conipieteiyWithdrawn trom the carrier7 the-locking rod may i be rotated to carrythe retaining coil beyond the edge oi' the carrier, as indicated in Fig.The loching rod may then be released to permit the spring 19 to draw theclip coii into engageinent with the edge of the carrier and thereby holdthe retaining means and the locking rod in their unlocked or openposition. The sleeve 2O is of such length that it ex tends into achannel 3 a suiicient distance to prevent its entire Withdrawal from thesaid tube when the locking ineens is withdrawn to the position shown inFig. 4. The inner end of the loclrin rod will aiways be guided by thesleeve t. When the iccking device is in the position shown in Fig. 4f,the indicator cups are free end may be rotated in either direction tobring the desired combi nation of numbers opposite the arrow head.

t is to be noted that the ioching ineans and the retaining coil 22 arewholly within the carrier when in their locked and retaining position.It is also manifest that the indicating means cannot become disarrangedWhile the carrier is in transit,
